Generator - Suzuki Jimny Service Manual

FAULTY INDICATOR LAMP OPERATION
Condition
Charge light does not
light with ignition ON
and engine off
Charge light does not go
out with engine running
(battery requires fre-
quent recharging)
How to use the temperature-corrected state-of-charge
graph
Suppose your S.G. reading is 1.28 and the battery temperature is
–5 °C (23 °F). Locate the intersection of the –5 °C line and the
1.28 S.G. line.
The intersection is within the "A" zone (shaded area in the graph)
and that means CHARGED STATE.
To know how much the battery is charged, draw a line parallel to
the zone demarcation line and extend it to the right till it meets
with the percentage scale. In the present example, the line meets
at about 85% point on the percentage scale. Therefore, the bat-
tery is charged up to the 85% level.

CAUTION:
• Do not mistake polarities of IG terminal and L terminal.
• Do not make a short circuit between IG and L termi-
nals. Always connect these terminals through a lamp.
• Do not connect any load between L and E.
• When connecting a charger or a booster battery to
vehicle battery, refer to this section describing battery
charging.

Trouble in charging system will show up as one or more of follow-
ing conditions:
1) Faulty indicator lamp operation.
2) An undercharged battery as evidenced by slow cranking or
indicator dark.
3) An overcharged battery as evidenced by excessive spewing
of electrolyte from vents.
Noise from generator may be caused by a loose drive pulley,
loose mounting bolts, worn or dirty bearings, defective diode, or
defective stator.
Possible Cause
Fuse blown
Light burned out
Wiring connection loose
IC regulator or field coil faulty
Drive belt loose or worn
IC regulator or generator faulty
Wiring faulty
CHARGING SYSTEM 6H-7
Correction
Check fuse.
Replace light.
Tighten loose connection.
Check generator.
Adjust or replace drive belt.
Check charging system.
Repair wiring.
